Lab
My personal cloud server and what's running on it.
Server
Ubuntu 24.04 LTS running on a DigitalOcean Droplet (1GB RAM, 25GB SSD, NYC3). Used for learning, hosting projects, and practicing real-world Linux administration.
Web Server
nginx serving this site over HTTP, with Certbot ready for HTTPS. Firewall configured with ufw, allowing only SSH, HTTP, and HTTPS traffic.
Security
fail2ban automatically bans IPs after repeated failed SSH attempts. SSH key authentication only — password login disabled. Root SSH access locked down.
Monitoring
Datadog agent running for real-time infrastructure monitoring — CPU, memory, disk I/O, and network metrics. Auth logs monitored for intrusion attempts.
